| Summary: | 碩士 === 國立高雄應用科技大學 === 資訊工程系 === 102 === Cloud computing has emerged as a promising paradigm for cost efficient and pervasive service delivery across data communication networks. While the computing and distributed system issues of cloud technologies have been extensively investigated, fewer attention has been devoted to the unique set of networking challenges to a cloud system.
In this paper, we propose a platform to dynamically build and manage virtual networks across multiple data centers. The specific contributions presented in this paper are the following: First, we propose a novel mechanism called VirtualTransits to transparently extend a virtual network across one or more data centers. Second, we present an integrated system to incorporate several important datacenter networking schemes into a coherent platform that enables the dynamic configuration and management of virtual networks both intra-cloud and inter-cloud. Third, we provide the results of performance measurements from the implementation based on real production networks.
